ClutchCoverLowerHoleGuideBarAdjustingPin 12. Install bar nuts and finger tighten only. Once the chain is tensioned, you will need to tighten bar nuts. CHAIN TENSION (Including units with chain already installed) WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. NOTE: When adjusting chain tension, make sure the bar nuts are finger tight only. Attempting to tension the chain when the bar nuts are tight can cause damage. Checking the tension: Use the screwdriver end of the chain adjustment tool (bar tool) to move chain around guide bar. If the chain does not rotate, it is too tight. If the chain is too loose, it will sag below the bar. BarNutsChainAdjustmentToolGuideBar(Bar Tool) Adjusting the tension: Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your saw. Always check chain tension each time before you start the chain saw. 1.

Slightly loosen bar nuts and loosen chain by turning the adjusting screw. Retighten bar nuts. 8. If chain is too loose, it will sag below the guide bar. DO NOT operate the saw if the chain is loose. NOTE: The chain is tensioned correctly when the weight of the chain does not cause it to sag below the guide bar (with the chain saw sitting in an upright position), but the chain still moves freely around the guide bar. WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury to the operator and/or damage the chain making it unusable. If the chain jumps off the guide bar, inspect each drive link for damage. Damaged chain must be repaired or replaced.
